Corona Borealis is a small constellation in the Northern Celestial Hemisphere.
It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations.
Its brightest stars form a semicircular arc.
Its Latin name, inspired by its shape, means "northern crown".

Other cultures likened the pattern to a circle of elders, an eagle's nest, a bear's den, or even a smokehole.

The brightest star is the magnitude 2.

The yellow supergiant R Coronae Borealis is the prototype of a rare class of giant stars—the R Coronae Borealis variables—that are extremely hydrogen deficient, and thought to result from the merger of two white dwarfs.
T Coronae Borealis, also known as the Blaze Star, is another unusual type of variable star known as a recurrent nova.
Normally of magnitude 10, it last flared up to magnitude 2 in 1946.
ADS 9731 and Sigma Coronae Borealis are multiple star systems with six and five components respectively.

Abell 2065 is a highly concentrated galaxy cluster one billion light-years from the Solar System containing more than 400 members, and is itself part of the larger Corona Borealis Supercluster.
Covering 179 square degrees and hence 0.
433% of the sky, Corona Borealis ranks 73rd of the 88 modern constellations by area.
Its position in the Northern Celestial Hemisphere means that the whole constellation is visible to observers north of 50°S. It is bordered by Boötes to the north and west, Serpens Caput...
